If Nikki Bella's date with Peter Kraus had been filmed for "The Bachelorette﻿," it would have ended with him strolling into an SUV without a rose. She just wasn't feeling it ... TMZ has learned.

Our production sources tell us ... while her date looked every bit like an episode of 'Bachelorette' -- which included a ride on a gondola and sipping wine -- fact is, there just weren't any sparks for her to wanna lock down a second date.

The big tell ... we're told Nikki couldn't muster the strength to pucker up and kiss Peter when he made his move. Yup, she left him hanging. We're told she freaked out and screamed "NO!!!" before pulling away.
